Folding Bicycle
This bicycle was designed to capture the classic beach-cruiser style, but also have the versatility and portability of a folding bicycle.
How it folds:
Step 1. The handlebars fold down and slide inward.
Step 2. The seat folds down over the tire.
Step 3. The entire bicycle folds in half.
The prototype was constructed of only wood, PVC, insulation foam, and existing bicycle tires.
